I have some questions regarding the point cloud metric equations.

1. The second sum in the equation of the chamfer distance goes up to n. Should it not be m instead?
2. When computing the one sided Hausdorff distance I get the following results:
   hausdorff distance a to b: (0.0418305276594696, 162053, 477034)
   hausdorff distance b to a: (0.005509044707867019, 771942, 3530)
   hausdorff distance: 0.0418305276594696
   Where the first two results are the one sided version and the last result is the normal version. Should the result of the normal version not be 0.0418/2+0.0055 like in the equation of the hausdorff distance? Or does the normal hausdorff distance just take the maximum of the one sided hausdorff distances?
   Thanks in advance!
